ACKNOWLEDGMENTS. 



It is fitting that I should acknowledge in a preeminent degree my 

 obligations to the lamented Dri Lapham, under whose direction as 

 chief geologist the earlier part of the field work, which forms the ba- 

 sis of this report, was performed. In addition to the inestimable value 

 of such direction to a young geologist, there was ever at my disposal 

 and furnished to my needs, a large fund of information concerning 

 local formations and the unwritten history of previous investigations. 

 "While nothing will be found reported without specific mention that 

 has not been a matter of personal observation, it is impossible to dis- 

 cern in how far that observation has been enriched by such assistance. 



My acknowledgments are also due to those who have been associa- 

 ted with me as assistants during the progress of the work. Of these 

 especial mention is to be made of the accurate and efficient aid of Mr. 

 L. C. Wooster, who assisted in the field work of each season; of Mr. 

 r. II. King, who sustained that relation with equal acceptance during 

 two seasons, and of Mr. G. D. Swezey, whose botanical observations 

 are especially to be noted. Efficient assistance was also rendered for 

 shorter periods and special service by Messrs. N. D. "Wright, Samuel 

 Shaw, S. E. Lathrop, Gr. L. Merriman, J. II. Chamberlin, and W. C. 

 Stevens, and in office work by "W. F. Brown, I. M. Buell, C. S. Bacon, 

 C. S. Douglas, and others. To Prof. E. P. "Whitfield I am also in- 

 debted for valuable suggestions in relation to paleontological ques- 

 tions. 



For the innumerable courtesies that have been received from citi- 

 zens in the prosecution of the work, and that in many instances have 

 been of the utmost value, I desire to express my most sincere thanks. 

 It would be exceedingly gratifying to me to be able to make specific 

 mention of these favors, and such acknowledgment has been made so 

 far as possible in the manuscript annual reports, but the list has now 

 swollen to such dimensions as to preclude its publication here. A 

 vei-y just legal acknowledgment has been made in the provision of the 

 law of publication and distribution, which entitles all who have as- 

 sisted in the prosecution of the survey to a full set of the reports, and 

 the lulfiUment of that provision will give me the utmost pleasure.
